  酸和酐的银催化脱羧偶联：1,2-二酮和芳基取代的乙烷的入口

  摘要：

  开发了银催化的羧酸和酸酐的氧化脱羧偶联反应，生成1,2-二酮和取代的乙烷。该反应可通过相应的α-酮酸，烷基酸和酸酐的脱羧作用来生成酰基或烷基，它们依次偶联以有效地构建新的C-C键。该反应代表采用自由基终止策略的羧酸脱羧替代方案。

  A process for manufacturing a hydroxylated isoflavone of the formula (I) given in the description comprises re-acting an appropriately substituted 2-hydroxydeoxybenzoin of the formula (II), also given in the description, with a formic acid anhydride of the formula HCOOCOR3, wherein R 3 signifies C 2-20 -alkyl or various other groups as given in the description, in presence of a base or in a solvent which acts as a base, and if necessary promoting the ensuing hydrolysis of the so-produced acylated form of the hydroxylated isoflavone of the formula I by acidification. Of particular interest as products of this process are the 5,7dihydroxyisoflavones, e.g. genistein (5,7,4′-trihydroxyisoflavone). Isoflavones display many useful biochemical effects.

  Twenty-five novel pyranochalcone derivatives were synthesized and evaluated for their in vitro and in vivo antiproliferative activities. Among them, compound 10i exhibited superior potent activity against 21 tumor cell lines including multidrug resistant phenotype with the IC50 values ranged from 0.09 to 1.30 mu M. In addition, 10i significantly induced cell cycle arrest in G2/M phase, promoted tubulin polymerization into microtubules and caused microtubule stabilization. Further studies confirmed that 10i significantly suppressed the growth of tumor volume in HepG2 xenograft tumor model. Our study demonstrated that 10i could have beneficial antitumor activity as a novel microtubule stabilizing agent. (C) 2013 Elsevier Masson SAS. All rights reserved.
